    • encodeBigEndian

      public static final void encodeBigEndian(int integer, byte[] buf)
      Encode integer as a series of 4 bytes into buf starting at position 0 within that buffer.
      Parameters:
      integer - The integer to encode.
      buf - The buffer to write to.

    • encodeBigEndian

      public static final void encodeBigEndian(int integer, byte[] buf, int offset)
      Encode integer as a series of 4 bytes into buf starting at position offset.
      Parameters:
      integer - The integer to encode.
      buf - The buffer to write to.
      offset - The offset within buf to start the encoding.

    • decodeBigEndian

      public static final int decodeBigEndian(byte[] buf)
      Decode a series of 4 bytes from buf, starting at position 0, and interpret them as an integer.
      Parameters:
      buf - The buffer to read from.
      Returns:
      An integer, as read from the buffer.

    • decodeBigEndian

      public static final int decodeBigEndian(byte[] buf, int offset)
      Decode a series of 4 bytes from buf, start at offset, and interpret them as an integer.
      Parameters:
      buf - The buffer to read from.
      offset - The offset with buf to start the decoding.
      Returns:
      An integer, as read from the buffer.

    • testBit

      public static final boolean testBit(byte v, int position)
      Bitfield utilities. Returns true if the bit at position is set in v.
      Parameters:
      v - the value whose bit is to be checked.
      position - the 0 based bit number indicating the bit to check.
      Returns:
      true if the bit at position is set in v.

    • clearBit

      public static final byte clearBit(byte v, int position)
      Returns v, with the bit at position set to zero.
      Parameters:
      v - the value whose bit is to be cleared.
      position - the 0 based bit number indicating the bit to clear.
      Returns:
      v, with the bit at position set to zero.

      Parameters:
      v - the value whose bit is to be set.
      position - the 0 based bit number indicating the bit to set.
      value - if true, the given bit is set to 1; otherwise it is set to 0.
      Returns:
      v, with the bit at position set to 0 (if value is false) or 1 (if value is true).
